The term “MLM company” isn’t exactly accurate because the company is not necessarily defined by the fact that it uses a multi-level marketing structure. Instead, a good MLM will be a product-centric company, meaning that it will be, for example, a cosmetics company that uses an MLM structure. Test the product of the company you are interested in; the product must be something that you would willingly advertise even if you weren't working for the company.
In other words, they built their nest egg in a dead or dying tree. They may not get along with their spouse any longer, don’t have a life or friends outside of work, have broken relationships with their children, or have let their health go in hopes of getting it back later. They essentially sacrificed some of the things that are most important to them for the benefit of trying to buy them back in retirement. As a result, when they get there, they can feel lost, out-of-sorts, and struggle with their transition.
I totally agree, Mary. You can lose soooo much more just by opening up a small storefront business. I was in the Spa Industry and then the economy tanked in late 2008. I did not renew my lease in 2009. Lost my several hundred thousand dollar build-out. Lost so much more than taking an MLM business seriously. Even if I would have front loaded on a ton of product, I still would have been better off. People spend $750 and get some business cards then do nothing and blame MLM.
